Excelsa Rambler
Walsh 1909
Small but full, shiny, bright red flowers in large clusters. Long, pale green canes and pale foliage. Flowers only once, but still one of thebest ramblers. Growth robust with canes up to 12-15 ft long. Drastic pruning of old shoots right down to the ground, immediately after flowering, is very rewarding. Also called Red Dorothy Perkins.

Editor's footnote:  The Senior Editor, who loves hardy climbers, wonders why Mr. O'Neal does not mention the Walsh climbers - all truly hardy; mostly single, and of delightful forms as well of great vigour.  Seemingly they are almost "out", though excelling most of the newcomers in sheer beauty.  At Breeze Hill we are establishing a long hedge-fence of Walsh beauties, in his memory, including Paradise, Evangeline, Hiawatha, Milky Way, Wedding Bells, Excelsa, Troubadour, Sweetheart, Minnehaha, and others. Notice the pleasant names!
